Abstract
An electrical connector assembly comprises an insulative housing, a center pin having a first end protruding out of the insulative housing and a second end disposed in the insulative housing, a metallic sleeve enclosing the center pin for forming a receiving room therein and a protection member. The center pin is configured as a hollow structure and defines a center space therein with an opening at the second end thereof. The metallic sleeve comprises a solder portion disposed in the insulative housing. The protection member completely blocks the opening of the center pin.
Description
The present invention relates to a plug assembly, and more particularly to a plug assembly in which a contact pin disposed within the plug assembly is plugged at its rear end.
An electrical connector assembly for transmitting audio or video signals is widely used in various electronic device, such as television, DVD Player, MP3 player and so on. The electrical connector assembly usually comprises an insulative housing, a tubular center pin held by the insulative housing and having a center space with an opening at an end thereof, a metallic sleeve held by the insulative housing and enclosing the center pin, a plurality of wires respectively terminated to the center pin and the metallic sleeve, and an overmold member covering the insulative housing and the ends of the wires. At present, the center pin and the metallic sleeve are inserted-molded in the insulative housing. Because the center pin has an opening thereof, the insulative material of the insulative housing may enter into the hollow space of the center pin through the opening during the molding process, as a result, once the plastic material enters the hollow space, it will make the center pin become rigid and lose its compliant capability. Hence, a new design which can solve the problem is required.
Accordingly, an object of the present invention is to provide an electrical connector assembly with a protection member.
In order to achieve the object set forth, an electrical connector assembly comprises an insulative housing, a center pin having a first end protruding out of the insulative housing and a second end disposed in the insulative housing, a metallic sleeve enclosing the center pin for forming a receiving room therein and a protection member. The center pin is configured as a hollow structure and defines a center space therein with an opening at the second end thereof. The metallic sleeve comprises a solder portion disposed in the insulative housing. The protection member completely blocks the opening of the center pin.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.
Reference will now be made to the drawing figures to describe a preferred embodiment of the present invention in detail. Referring to FIGS. 1 to 7 , an electrical connector assembly according to a first embodiment of the present invention is provided.
Referring to FIG. 1 and FIG. 3 , the electrical connector assembly comprises a main body 100, a coat member 200 covering the main body 100 and a cable 300 with two wires 301 for contacting with the main body 100.
Referring to FIG. 3 and FIG. 4 , the main body 100 comprise a housing 1, a center pin 2 disposed in the housing 1, a metallic sleeve 3 enclosing the center pin 2 and a protection member 4. The center pin 2 is tubular and comprises a first end 21, a second end 22 and a rib 23 closer to the second end 22 and protruding outwardly. Referring to FIG. 5 , the center pin 2 is configured as a hollow structure and defines a center space 20 therein with an opening at the second end thereof. The protection member 4 can be inserted into the center space 20 via the opening. The protection member 4 comprises a head portion 42 and a tip portion 41 extending from the head portion 42. The tip portion 41 can be inserted into the center space 20 and the head portion 42 locates outside of the center space 20 to cover the opening of the second end. The tip portion 41 is short than a length of the center space 20, so the center space 20 is not fully stuffed by the tip portion 41. The center pin 2 can be distorted or bent appreciably duo to its own flexibility. The rib 23 can prevent the center pin 2 releasing from the housing 1. The metallic sleeve 3 comprises a tubular base 31 and a solder portion 32 extending from the base 31.
Before molding of the main body 100, the tip portion 41 of the protection member 4 is inserted into the center space 20, then the center pin 20 is placed in a mould and a die core is placed behind the head portion 42 of the protection member 4. Then plastic material is injected into the mould and the main body 100 is formed.
Referring to FIG. 3 , FIG. 4 and FIG. 9 , the main body 100 has a first channel 101 on a side thereof, a second channel 102 on another side thereof, a first hollow 103 communicating with the first channel 101 and a second hollow 104 communicating with the second channel 102. After molding, the second end 22 of the center pin 2 is disposed in the housing 1 and partly exposed in the second hollow 104, the first end 21 of the center pin 2 protrudes out of the housing 1, the solder portion 32 of the metallic sleeve 3 is held by the housing 1 and locates in the first hollow 103, and the tubular base 31 encloses the center pin 2 to form a receiving room 105 for receiving a mating electrical connector, which can be seen from FIG. 2 . Referring to FIG. 6 , FIG. 7 and FIG. 9 , a gap 106 going through the housing 1 is formed, because during the molding process, the die core is placed behind the protection member 4. The width of the gap 106 is equal to the width of the die core. The die core can stop the flowing insulative material from running against the head portion 42 of the protection member 4, which can protect the head portion 42 being melted. The die core can be a small one to avoid the weakest portion of the head portion 42 being run against, in this condition, the width of the gap 106 is smaller, and a part of a back face 420 of the head portion 42 is exposed in the gap 106, as shown in FIG. 7 . The die core can be a big one to avoid the whole back face 420 of the head portion 42 being run against, in this condition, the width of the gap 106 is bigger, and the whole back face 420 exposes in the gap 106 in a second embodiment as shown in FIG. 8 and FIG. 9 .
Referring to FIG. 2 and FIG. 4 , the cable 300 comprises a pair of wires 301. One of the wires 301 can electrically contact with the solder portion 32 of the metallic sleeve 3 via going through the first channel 101. The other wire 301 can electrically contact with the center pin 2 via going through the second channel 102.
Referring to FIG. 1 , the coat member 200 covers the main body 100 and one end of the cable 300. Some ribs protrude outwardly from the coat member 200 for an operator to hold.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
